Dampening Type 2 Properties of Group 2 Innate Lymphoid Cells by a Gammaherpesvirus Infection Reprograms Alveolar Macrophages

Using murid herpesvirus 4, a mouse gammaherpesviruse, scientists showed that after infection, lung-resident and recruited group 2 innate lymphoid cells exhibited a reduced ability to expand and produce type 2 cytokines in response to house dust mites, thereby contributing to protection against asthma.
